An easily installable enhancement for replacing the reflective surface area for a satellite dish and method for using an installed dish as a reference, allowing the installation of a dish with added features without re-acquiring the satellite signal or reaiming the dish. In one variation, the enhancement includes a reflector addition, which is fitted with fasteners that locate the reflector against the existing dish. This variation includes use of the original feed horn, which is relocated using a feed horn support extension. This variation is also designed to avoid the "shadow" of the feed horn and its support arm, and to minimize the reflective surface area at the lower end of the dish, which reduces collection of such interfering material as snow, rain, and debris. In variations using increased reflector size, the enhancement reduces loss of signal during inclement weather or in other situations in which the satellite signal is partially blocked. In one variation, the added reflector is a standard parabolic reflector, such as a 24-inch dish, superimposedly installed over the original reflector. In a second variation, the added reflector is a custom designed parabolic surface that extends the existing dish surface only at the original reflector's circumferential edge. In a third variation, the added reflector is ring-shaped and similarly attached at the outer edge of the original reflector. Also disclosed is a system for attaching and making additional adjustments for applications using a more complex replacement reflector, such as for receiving signals from multiple satellites.
